ELECTRICAL WATER-HEATING DEVICE.

Application filed February 27, 1922. Serial No. 539,523.

To all whom it may concern:

Be it known that I, SVEND Gonnov, residing at Miami, in the county of Dade and State of Florida, a subject of the King of Denmark, have invented certain new and useful Improvements in Electrical Water"- Heating Devices, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof. 7

My invention relates to electric heating devices forv heating water or other liquids and has for its object to provide a device for this purpose. which will be simple and inexpensive in construction and will be particularly adapted to utilize an alternating current to heat a stream of water as it flows through pipes.

A further object of the invention is to provide a device of this character in which the -full energy of the current will be utilized for heating purposes.

A further object of the invention is to provide a device for this purpose which can readily be connected in the usual household water. supply system.

, With the above indicated objects and other objects hereinafter explained in View,

my invention consists in the construction and I combination :of elements hereinafter described and claimed:

Referring to the drawings: r s Figure 1 1s a central vertical sectional conducting material here shown as a section of iron or steel pipe having at its 'up-, per end a cap 2- screw threaded to the end of the receptacle and having a central screw threaded opening 3 adapted to receive a suitable delivery pipe (not shown). The lower end of the receptacle is screw threaded into the end of a collar 5 having on one. side a. screw threaded nipple Gto receive an inlet pipe. Into the lower end of the collar 5 is screwed a plug 7 To the plug 7 is screwed a guard box 8 extending below the plug and having in its base, an opening 9 into which is inserted a ring 10 of insulating mate-' rial.

The plug 7 is provided with oppositely arranged openings in which are screwed plugs 11 and 12 of insulating material through which extend screws 13 and 14 respectively. On these screws are secured horizontally extending lower ends 15 and 16 of metallic plates 17 and 18 which extend upward nearly to the upper end of receptacle 1, the upper ends of thesev plates being held at a suitable distance apart and away from the walls of the receptacle byto firmly clamp the ends 15 and 16 against the washers 23 and 24 by nuts 25 and 26 hearing against washers 27 and 28 which in turn bear against discs 29 and 30 of insulting material.

The ends ofwires 31 and 82 lead from a source of alternating current here indicated diagrammatically as an alternate current generator.

In operation the cold water pipe of a usual water supply system is connected with nipple 6 of the collars and the end of the delivery pipe is screwed into opening 3 in the cap 2. The wires 31 and 32 being in circuit with the source of alternating current, and the water being turned on, the electrical impulses pass to the plates 17 and 18 and, through the water, from one plate to the other and, as the walls of the receptacle are of conducting material in circuit with ground through the pipes of the water supply, also pass through the water to the receptacle. Current leakage is thus utilized to aid in heating the water byits passage through it.

In the construction shown the receptacle, I

its cap, the collar 5, and the pin 7, are all formed of stock pipe fittings sot at the device is inexpensive'to construct. The plates 17 and 18 are simple in construction and the insulating plugs ll and 12 and tha screws 13 and 1% and the insulating ring 10 are heated above the boiling point and steam generated.

Having thus described my invention, what I claim is 1. In an electrical water heating device the combination of a receptacle of conducting material adapted to contain liquid to be heated provided with means for connecting an inlet and delivery pipe thereto, insulated plates of conducting material within the receptacle spaced apart and away from the Walls ofthe receptacle and a source of alternating current connected with the plates, the inlet and outlet pipes being connected to ground.

2. In an electrical water heating device, the combination of a cylindrical receptacle of conducting material provided at one end with a cap having an openin for a delivery pipe, and provided at the ot er end with a "plates of con collar having a nipple to receive an inlet pipe, a plug carried by the collar provided with insulating material adapted to support plates of conducting material, said plates of insulating material extending into the receptacle at a fixed distance from each other and from the walls of the receptacle, and means for connecting the plates with a source of alternating current.

3. In an electrical Water heating device, the combination of a cylindrical receptacle of conducting material provided at one end With a cap having an opening for a delivery pipe, and provided at the other end with a collar having a nipple to receive an inlet pipe, a plug carried by the collar provided with insulatin material adapted to support ducting material, said plates of insulating material extending into the receptacle at a fixed distance from each other and from/she walls of the receptacle, means for connecting the I plates with a source of alternating current, an'inlet and a delivery pipe forming part of a grounded Water supply system.

In testimony whereof I hereunto afix my signature.
